JOS. ALEXANDER BLOOM, OF PHILADELPHIA. PENNSYLVANIA IMPROVEMENT IN PUMPS FOR DEEP WELLS.

Specification forming part of Letters Patent No. 52.019, dated January 16, 1866.

'To all whom it may concern:

Beit known that I, JOS.ALEXANDER BLOOM, of Philadelphia, in the conntyof Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Pumps for the Use of Oil-\Vells and Mines; and I do hereby declare that the following is a full, clear, and exact description of the apparatus, and of its functionary parts, as represented by the sectional drawings making a part of the specification.

The machine 0' apparatus consists of asmooth-bored cylnder. Figure l, which is divided by the plate B into two apartments, (marked 1 and Il.) Through this plate. passes the piston-rod U, air-tight.

The apartment I acts as a draw and force pump, and connects with the well-tubing I), through which the liquid is to be pumped up to the surface, entering by the valve a on the upward movement of the piston-head I Land on its downward movement is forced through valve 1), and through the tube 0, to the surface.

The apartment It acts as adouble or single pneumatic pump, as may be desired, forcing the atmospheric air admitted by the valves d and 0 through the valves f and ginto the pipe F. This pipe descends outside. along the cylinder and enters the. well-tubing D'at a convenient point, suppose at r, and leads the air inside of the well-tubing to near the bottom of the well, and there discharges through the valve it, either immediately above the bottom valve, 4', into the well-tubing, or some tive or ten feet above said valve, and immediately over the lowermost partition-plate, k. These partition or check plates are inserted in the well-tubing at distances from twenty to twenty-livc feet apart, according to the length of one tubing-link. They are provided with an upward-opening valve, 1), for the ascension of the oil, &c., and with an opening, 8, for the passage of the air-conducting pipe F, as represented in Figs. 2 and 3.

In the lower end of the well-tubing is a hollow metal ring or hollow metal chamber, 10, inserted. Upon it rests the bottom valve, 2'. A wire, a, from a. galvanic battery, V, on the surface, leads to this hollow metal chamber, Fig. 4, through a non -conductor, and coils in said chatnber.

At the end of the well-tubing is the bottom piece, 0, of the well-tubing I) attached, perforated by holes similar like the so -ca-lled suorcr on pump-pipes. Y

By means of the galvanic battery suflioient caloric is imparted to the bottom valve, 1', and to the bottom piece, 0, of the well-tubing l), to prevent the adhesion of or clogging by parafiine, and to prevent ignition of inflammable gases, See.

The whole pumping apparatus, in all its parts except the valves, is made of iron.

What I claim as my invention, and desire to secure by Letters Patent, is-- 1. The construction and arrangement of the hydraulic and pneumatic pumpchambers I and It in one cylinder, by means ot'the division-plate B, aflbrding a steady guide to both pistons E and E, in combination with the airconductiug pipe Fand well-tubing D, as shown, and substantially as described, together with system of valves.

2. The construction and arrangement of the hollow metal chamber '10 on top of the bottom piece, 0, iucloillg hermetically a Wire coil connected with any galvanic apparatus on the surface, for the purpose and substantially as described.

JOSEPH ALEXANDER BLOOM.
